Cardiologist self-referral of MPI remains a concern
August 6, 2019 -- Overall usage of standard myocardial perfusion imaging (MPI) exams has declined, but cardiologists are performing a higher share of these studies, according to research published in the August issue of the Journal of the American College of Radiology. Read More
AI algorithm could reduce wrong-side medical mistakes
August 5, 2019 -- Wrong-side medical procedures are among the most devastating -- and preventable -- errors in healthcare. But what if you could stop wrong-side mistakes simply by analyzing radiographs with a machine-learning algorithm? A research group gave the idea a try and described their findings in the August edition of the Journal of Digital Imaging. Read More
Routine PET field-of-view enough for pediatric lymphoma
August 5, 2019 -- A routine "eyes to thighs" field-of-view with FDG-PET/CT scans is more than adequate to stage and monitor disease in a majority of pediatric patients with lymphoma, according to a study published in the August issue of the Journal of Nuclear Medicine. Read More
AI accurately estimates bone age on 3D hand MRI
August 5, 2019 -- An artificial intelligence (AI) algorithm can estimate bone age in children and adolescents from analysis of a 3D hand MRI exam with a very high level of accuracy, according to research published online July 31 in Medical Image Analysis. What's more, it can also perform well on wrist radiographs. Read More
